Application filed January 20, 1913. Serial No. 743,114.

To all whom it may concern Be it lmown that I, EDWARD J. VON PEiN, a citizen of the United States, residing at Dayton, in thevcounty of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to accounting machines and more particularly to the recording mechanism thereof.l

In a grocery or a business of a similar i nature, which doesa credit business, it is'desirable to keep an accurate record of the credit transactions and to keep the accounts of each customer segregated from the accounts of the other customers. It is further desirable to record each transaction on a sales slip and a duplicate, so that one slip may be given to the customer and the other be retained by the proprietor 'of the establishment, and thus avoid controversies between the parties to the transaction and prevent mistakes or fraud.

The principal object of this invention is to provide areceptacle for recording and segregating the lcredit transactions of each customer on` a detail strip, contained in the receptacle, andit is a further object of this invention to provide means for recording on duplicate sales slips a record of each credit transaction. In accomplishing these objects a receptacle for the account of each customer is provided with a detail strip and platen, the platen being given a movement of invariable extent against a set of type carriers, upon the operation of. keys governing the v mechanism for the recording of each transaction. The platen is given this invariable movement by the invariable movement given n a receptacle carriage by means of the main operating mechanism. Themachine is also provided witha guideway for a duplicate sales slip, the slip being placed in the guideway by the proprietor conducting the business or by one of his clerks, with a platen given invariable movement against type carriers, whereby impressions of the transaction are taken on the sales slip, and with a pair of .feed rollers given an invariable movement by the proper operating mechanism so that the sales slip may be fed with which accompany and forni partof thespecication.

Figure 1 is a transverse vertical section of a machine, well known on the market, with the present invention applied thereto. Fig.

2 is a detail of the special bank of keys, and

mechanism coperating with these keys. Fig. 3 is a detail plan showing the receptacle for the duplicate sales slips and the detail strips. Fig. 4 is a detailed view of the mechanism for operating the feed rollers, which feed the sales slip. Fig. 5 includes two views of the sales slip and the duplicate, a top and a side view.

4F or the sake of illustration, these improvements have been shown applied to a type of machine well known on the market and exemplified in the patents to Cleal and Reinhard #580,378, issued April 13, 1897,

-to Frank I-I. Bickford, No. 690,554, Jan. 7

1902, and to Thomas Carroll, No. 754,049, issued March 8, 1904. In these patents the principal movements of the machine are clearly shown and described.

Referring to thel accompanying drawings, 1 (Fig. 1)v represents the amount keys which serve to control the differential motion of the various parts as fully described in the Carroll, and Cleal and Reinhard patents. The machine is driven by means of a handle 2 journaled on a stub shaft 2a fastened to the machine frame. Rigid with the handle 2 is a gear 3a meshing with a gear 3 fast on a shaft 29, and this latter gearengages with a gear 4 rigidly mounted on a shaft 57.' On a shaft 5fL is fastened a gear 5 which engages with the gear 4. Rigid with. the gear 6 which meshes with a gear 5 in a gear on the shaft 7. shaft 7 so that when the crank handle `is turned the box cain is rotated by means of A box. cam 8 is fast on this this train of gears just described. This box cam 8 controls the impression mechanism,

as will be explained. Each receptacle 9' is separated into two apartments, the forward one being used as a iile for the duplicate sales slips and the rear one, which is accessible only by means of al key 12, contains a detail strip 13 and a platen14. This receptacle is for the purpose of recording and segregating the credit accounts of each cuast'omer. A carriage 10 for the receptacles 1s pivoted on the frame of the machine by. the rod 15, so that the receptacle may be given an invariable movement by the invariable movement of the following described operating mechanism. A roller 16, projecting from the rear end of an arm 23, engages in the groove of the box cam 8. This arm 23 is loose on a rod 17, which projects from the supporting frames 18. Extending for` wardly from the arm 23 is an arm 19, which has securedv to its 'forward end a link 20, the

a lower end of this link being secured to a lug 21 by a pin. This lug `is fast to the top of the rear end of the receptacle carriage 10. Vhen the box cam 8 is rotated, the rear end of the arm 23 is raised,- due to the shape of the cam groove, and the rear end of the receptacle is lowered through the link 20 and the arm 19. The purpose of lowering the receptacle with an invariable movement is to bring the platen 14 which is fast on the receptacle against type carriers 22, so that an impression may be made on the detail strip 13 of each credit transaction.

Cams 24 coperate with disks 25 to feed the detail strip between the taking of impressions. The cams 24 are fast on a shaft 26 which is supported by the frame 18. Fast to the same shaft 26 is a gear 27 which engages with a gear 28 rigid with the large gear 3. The disks 25 are fastened to a roller 25a, upon which the detail strip is wound after it is printed. The construction of this mechanism is such that the c ams 24 engage once during each operation of the machine with the disks 25, thereby rotating the disks and roller 25a so that thedetail strips 13 are fed a space before the taking of an impression.

When the receptacle is inserted in the machine it is desirable to provide means for holding it in position while an impression is being taken. This is done by means of the sharp downward projecten on the forward end of an arm 64 engaging in a recessin the top of the receptacle as shown in Figs. 1 and 3. The arm 64 is loosely mounted on the shaft 49 and extending rearwardly from this arm is another arm 65, which at its rear end has a projection engaging with a cam 66. This cam is fast on the shaft 7 and is so constructed that, after an impression on the detail strip is made, the cam projection engages with theprojection on the prevent this a special bank of keys is provided, as shown in Fig. 2, the key 30 controlling the registration of cash transactions, the keys 31 and 32 controlling the operation of the machine for the recording of credit and received on account transactions. Key 33 is for paid out transactions. Adjacent the special bank key is a segment 38 loose on the shaft 39. The pins on the special keys 30, 31, 32 and 33y engage in elongated recesses, 34, 35,. 36, and 37, respectively in the segment 38. The recesses 34 and 37 are so v inclined that, when the cash or paid out key is pressed, the pin on the key pressed comes into operative relation with the upper face of the recess and raises the forward end of the segment. When the segment is raised a shaft 44 is rocked through a link 40 which is secured to the segment by a pin 41 and to an arm 42 by a pin 43, the arm 42 being rigidly secured to the shaft 44. To this shaft is fast a'crank arm 45, which is connected at the other end to a link 46 by a pin 47. The rear end of this link is secured to a crank'arm 48 which is fast on a sleeve 48a surrounding a shaft 49, as shown in Fig. 3. Fast on the same sleeve is an yarm 50 and it is therefore obvious that when the cash or paid out key is pressed the rocking of the shaft 44, as explained, will raise the lower end of the arm 48 and hence lower the forward end of the arm 50. The forward end of the arm 50 has a projection forming a shoulder 51, so that when the' cash or paid out key is pressed the arm 50 is lowered sufficiently for the shoulder to engage with the rear end of the receptacle 9, should the re* ceptacle be inserted into the machine after the key has been pressed. When the cash or paid out key is not pressed the shoulder 51 of the arm 50 is not in the path of an approaching receptacle and the receptacle can be inserted. Further, when the receptacle is in the machine the cash or paid out key cannot be operated as the arm 50 cannot be low.

so that the nature of the transaction will be indicated. To provide for this the following mechanism is used. In Fig. 2, 52 is the usual detent plate which is operatedas fully described in the Cleal and Reinhard and Carroll patents. On this detent plate is a pin 53 which, when the detent plate is raised as explained in the patents cited above, engages with the lower face of the upper projection on the forward end of an arm 54, this arm being rigidly secured to a shaft 54 so that when the detent plate 52 is raised this shaft is rocked. Extending rearwardly from the shaft 54 and fast to it is an arm 55. This Vto arm has an upward extending projection, which, before one of the special keys is pressed, is in engagement with the radial face of the recess in a disk 56 which disk is rigidly mounted on the shaft 57 with the ear 4. lVhen the detent plate is raised the shaft 54 is rocked, the rear end of the arm 55 is lowered, and the projection is taken out of engagement with the disk so that the v.crank handle 2 can be operated.

This invention being for the purpose of recording credit transactions on a detail strip, a mechanism is provided which prevents the operation of the machine to register a credit or received on account transaction except when a receptacle is in the machine. and loosely surrounding the same shaft is a sleeve 58 to which is fastened an arm 60. When a receptacle 9 is inserted, it engages with the curved arm 86 and lowers it, thereby rocking the shaft 49, and lowering the arm 60 by a shoulder on a collarl 61 secured to the shaft engaging with a shoulder on the sleeve 58, as shown in Fig. 3. rlhis lowering of the arm 60 by the engagement of the receptacle with the arm 86 takes the projection` on the forward end of the arm 60 out of engagement with an arm 62, which is fast on the shaft 54 and permits the rocking of the shaft when the detent plate is raised, as has been explained.

rIhe spring 87, which is under tension between pin 88 projecting from the frame work of the machine and the pin 89 on the arm 60, normally holds the arm 60 in engagement with the arm 62. It can readily be seen that this same mechanism just described, is employed to partially eject an inserted record retaining receptacle from the machine after a printing impression is taken on its detail strip 13 from the type carriers 22. The cam'66 is so designed that the pro-` jection on the arm 64 will be carried out of engagement with the inserted retaining receptacle just after the arm'62 is carried back to its normal position (shown in Fig. l) so `that the spring 87 raises the arm 60 to normal position, and in this manner the arm 86 is rocked upward forcing the inserted receptacle forward so that when the arm 64 An arm 86 is fast on the shaft 49 is lowered to its normal position its projection will not engage in the coperating recess in the top of the inserted receptacle.

When it is desired to register cash or paid out transactions, it is necessary that the arm 60 be taken out of engagement with the arm 62 so that the crank handle may be operated. This is accomplished by the following mechanism. On the same sleeve 48a on the shaft 49, to which the arm 48 is made fast, is a shoulder 63, which can engage with a shoulder on the sleeve 58. When the cash or paid out key is operated the arm 48 is raised, and the shoulder on the sleeve 48a engages with the Shoulder oni the sleeve 58 and thereby lowers the arm 60, taking the projection on the forward end of the arm 60 out of engagement with the arms 62,'and hence allowing the disengagement of the arm 55 from the disk 56. The crank handle can then be operated.

In addition to the mechanism just described whereby the insertible record strip holder controls the operation of the special keys, it is to be understood that the illustrative lmachine is so constructed that when charge and paid out transactions are entered, the totalizer 100 is not operated to add the amounts. The mechanism whereby this is accomplished is not shown in the accompanying drawings but is fully shown and described in the Bickford patent hereinbefore mentioned.

It will be seen that in the machine as so far described, an impression of each credit transaction istaken on a detail strip in a receptacle by means of a platen mounted in each receptacle and given an invariable movement against type carriers by the invariable movement of the operating device, as has been described, the detail strip being fed between impressions by the invariable movements of a feeding device.

Mechanism is provided in this invention for recording on a duplicate and an original sales slip the character and amount of each credit transaction, one slip being kept bythe proprietor and the other given to the customer as a receipt or record of the transaction. This mechanism is constructed and operated in the following manner.

A guideway 67 is for the purpose of holding the sales slips while receiving impressions recording credit transactions. The platen mechanism consists of a frame 68 mounted on a cross shaft 7 0, and the frame carries a pin 69 engaging a cam 73 and at its forward end platen 70. At the rear end of this frame is rigidly secured an arm, 71 which at its lower end has attached a Spring 72, which is under tension and thereby tends to force the platen against the type carriers. Fast on a shaft is a cam 73, this cam being so constructed that twice during every rotation of the shaft 65 by the intervening gears, it lowers the platen frame 68 tensionthis roller being on the rear end of an arm 76. This arm is loose on the shaft 77 and extending forwardly from it is an arm 78. The forward end of thislatter arm supports a feed roller 79 mounted on a pin 82. The groove in the cam 74 is so constructed that, after the first impression is made on the sales slip, it will bring the feed rollers 79 and 81 into contact by lowering the arm 76 and thereby raising the roller 79. The rear end of a pitman 80 is forked and straddles the shaft 65. The forward end of this pitman is secured near the periphery of the feed roller 79 by a pin 83. On this pitman is a roller 84 engaging in the groove ofthe cam 74 shown by dotted lines (Fig. 4). This latter cam groove is so constructed that as the lower feed roller comes into operative relation with the upper feed roller the lower feed roller is given a slight movement in the counter clockwise direction thereby feeding the sales slip so that an impression may be taken on the duplicate slip which is longer than the original.

The clerk places the sales slip into the guideway 67, depresses the credit or received on account keys and then the amount keys, and turns the crank handle thereby rotating the cams on they shaft 65. During one rotation the cam 73 twice operates the frame 68, the first time impressing the amount and character of the transaction on the original slip, the second time making a like impression on the duplicate. Between the time for taking these two impressions j the roller 79 is raised into contact with the upper roller and the pitman 80 given a short rearward movement by the cam groove, thereby moving the sales slip from its original position into a position in which the duplicate will receive an impression.

The operation of the machine is as follows: The sales slip is made out in the usual way and placed in the guideway 67, and the receptacle assigned to the customer to whom credit is being extended is inserted in its carriage. The ke.y corresponding to the character of the sale is then pressed and the amount keys are operated. Upon turning the crank handle the mechanisms of the present invention are set into motion. The platen being carried in the receptacle is lowered against the type carriers because the detail strip is fed. During the latter I part of the operation the arm 64 is disengaged from the receptacle by the raising of the arm through the lowering of the arm 65 by the cam 66, so that the receptacle may be withdrawn after the recording of the transaction. While an impression is being made on the detail strip, as just explained, the cam 73, because of its construction opcrates twice the platen frame, and the spring 72 brings the platen 70 against the type carriers, the first time making an impression on the original sales slip and the second time making an impression on the duplicate. After the first impression is made the feed roller 79 is raised and given a slight movement in a counter-clockwise direction because of the construction of the grooves in the feed cam 74, as described. This movement of the lower feed roller brings it into operative relation with the upper feed roller and thereby feeds the sales slips so that the duplicate will be in a position to receive an impression. By these mechanisms the object of the invention is accomplished as a permanent record is taken on the detail strip in an inserted receptacle, while a receipt or record of the transaction is given to the customer in the form of a sales slip, the other sales slip being placed in the receptacle under the spring holder 85.

While the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.
